OPTIVUS S-AI PRO H4 LED Bulbs 9-32V 100W 3000K-8000K with APP Control

OPTIVUS S-AI PRO H4 100W 3000K-8000K LED bulbs are an advanced automotive lighting solution featuring adjustable color temperature and smartphone APP control.

The bulbs are designed for headlights using the popular H4 bulb base and provide both low-beam and high-beam (Hi/Low Beam) functions from a single bulb.

This dual-beam configuration is a defining feature of the H4 standard. Conventional H4 halogen bulbs use two filaments to provide high and low beam functions, while an LED replacement uses LED emitters and electronic control to provide the corresponding lighting modes. H4 is specified for both high-beam and low-beam applications.

A major feature of the OPTIVUS S-AI PRO series is adjustable color temperature from 3000K to 6000K.

This allows the driver to select the preferred light tone depending on weather conditions, road environment and personal preference.

3000K provides warm yellow light.

4300K provides warm white illumination.

5000K provides a natural neutral-white appearance.

6000K provides modern cool-white LED illumination.

Available lighting settings can be controlled through a compatible mobile APP, allowing the user to adjust the light directly from a smartphone without removing the bulbs.

The model has a stated power rating of 100W and uses an active cooling system with a fan and metal heat sink to dissipate heat generated by the LED components.

The wide 9-32V DC operating range expands compatibility with different automotive electrical systems, provided that the headlamp, electrical system and H4 mounting configuration are compatible.

H4 High Beam + Low Beam

One of the main advantages of the H4 design is that a single bulb provides two headlight functions:

LOW BEAM — dipped beam

HIGH BEAM — main beam

The H4 automotive standard is widely used for this dual-beam application.

H4 Applications

The H4 standard is widely used in headlamps where one bulb provides both high and low beam. Standard automotive H4 bulbs commonly use the P43t/P43t-38 base.

H4 applications may include:

passenger cars;

SUVs;

pickup trucks;

minivans;

vans;

light commercial vehicles;

motorcycles and other compatible two-wheel vehicles.

Depending on model year, market and trim level, H4 bulbs may be found in selected vehicles from:

Volkswagen, Skoda, Renault, Dacia, Peugeot, Citroën, Fiat, Ford, Opel, Toyota, Nissan, Mitsubishi, Suzuki, Hyundai, Kia, Mazda, Honda, Subaru, Chevrolet, Daewoo, Lada and other manufacturers.

Important Compatibility Information

Before ordering, always verify:

vehicle make;

vehicle model;

production year;

trim level;

vehicle market specification;

headlamp design;

original bulb marking;

connector type;

mounting system;

available space behind the bulb;

clearance for the cooling fan;

ability to reinstall the original headlamp dust cover.

Vehicle compatibility should not be determined by make and model alone, because different headlamp configurations may use different bulb types.

Some vehicles equipped with sensitive bulb-monitoring electronics may require an additional CANBUS decoder after replacing halogen bulbs with LED units.
